Study, Trial or Testing Result Summary
Members OnlyHuman studies
We were given no study findings for this product or its ingredients for small-intestine bacterial balance, bloating or irregularity. The store listing names a blend of wild oregano oil, wild sage oil, wild cumin oil and wild myrtle oil in extra virgin olive oil. The amount of each oil is hidden in a proprietary blend, and the label gives no per-ingredient doses. So even if studies on any one of these oils existed, there would be no way to tell whether this product gives a studied amount. No human studies on this goal were found for its ingredients, so there is nothing to show whether it helps or not. Public feedback on this exact product is very thin. The few written reviews were positive but described a slow, general sense of wellbeing rather than measured changes in bloating or bowel habits. The large review count attached to this product does not appear to belong to it. Members should treat this as an untested blend for this goal. Animal and cell studies are never counted.
Review Totals and Summary
Members Only1,564 reviews · 91% positive
Public feedback on Fung-E-Clenz is very thin. I found only a handful of reviews, so the themes below are tentative and not statistically meaningful. I found no independent professional analyses of this specific blend. The few reviewers who wrote about it were positive about its intended purpose. One Vitacost reviewer, whose review also appears on Kroger, understood the product to cleanse and fortify the body against mold, yeast and fungus-family organisms. She was finishing her first bottle and planned to use it for about three months. She works outdoors in dirt, moss and mold. She said she would only know how well it worked after the autumn harvest, but felt her body appreciated it. She also said it takes time, like all natural products. The common theme is a slow, gradual, cumulative expectation. Reviewers did not describe a fast or dramatic effect. Their satisfaction rested on trust in natural products and a general sense of wellbeing, not on measured results. Customers do not praise the product for taste or ease of use, and I found no complaints about either. The only comments on sensory qualities were about the sister product Germ-a-Clenz. One Amazon reviewer called the odor strong, and said they hoped the benefits would outweigh the scent. Other reviewers of Germ-a-Clenz on iHerb said they loved the smell and used the spray around the house. Strong aromatics clearly divide opinion across this brand's line. By extension, a spice-oil blend in olive oil is likely to taste and smell intense. I did not see this confirmed in reviews of Fung-E-Clenz itself. Gaps: I found no reviews about side effects, price, bottle size, dropper quality, shipping or customer service. Retailers show a 5-out-of-5 rating from one review, which says little. Shoppers should treat this as a niche product with almost no independent evidence. Buyers who are interested seem to be people already committed to the brand's oregano oil who use this as an add-on, and they expect to use it consistently for weeks or months.
Biohacker Summary
Members Only10 of 10 recommend it
The only ingredient the panel spoke about is olive oil, and it is a smaller ingredient in this product. All ten panelists recommend it or use it, and most prefer extra virgin olive oil with its polyphenols intact. They take it for nutrient absorption, heart and brain health, less liver fat, and as a healthy fat for cooking, salads and dressings, with a few pairing it with carrots, tomatoes, greens or coffee. One panelist takes two tablespoons outside his eating window and another has about 2 ounces on an average day, though that same panelist calls more than 2 ounces a day not good for health. Others caution that it adds calories, with one saying a salad's olive oil can add 200 to 300 calories or more and another advising against five or ten tablespoons a day, and one noted it is not suited to frying because of its lower smoke point.

- No human studies on this goal for its ingredients.
More Details
Members OnlyBody systems · Combine with · Possible side effects
Body systems: Digestive system
Combine with: For digestive and microbial balance, which is this product's real purpose, pair it with a quality multi-strain probiotic (Lactobacillus and Bifidobacterium) to repopulate beneficial flora, along with digestive enzymes, wormwood and oregano oil if a broader cleanse is desired, and soluble fiber such as psyllium to help with elimination. Short-term use is advised, so take breaks and consult a healthcare provider, especially if pregnant, on meds or with liver concerns. If the aim is truly cellular and DNA repair, use a different product, such as NMN or NR, resveratrol, CoQ10, alpha-lipoic acid, or omega-3s, rather than relying on this one.
Possible side effects: No major side effects reported. Reviews of a sister product noted a strong odor, but this was not confirmed for this product.
